ADVERTISING DISPLAY DEVICE.

Specification of Letters Patent.

Patented Aug. 18, 1914.

Application filed January 30, 1913. Serial No. 745,061.

To all 'whom 'it may concern:

Be it known that we, HYMAN GRAD, a subject of the Emperor of Austria-Hungary, SYDNEY H. KLEEnEno, a subject of the' King of Great Britain, and WILLIAM Hannis, a citizen of the United States, all residents of Newark, in the county of Essex and State oit.' New Jersey, have invented certain Improvements in Advertising Display Devices, of which the following is a specification.

This invention relates more particularly to that class oi advertising display devices in which the advertisement is projected by means of a lantern onto a suitable screen.

The objects of the invention are to vide an automatic device of this character requiring minimum attention; to provide such a device which will display successively a plurality of advertisements; to provide an intermittent movement of the slide holder whereby the display of an advertisement may be given a definite interval of time and the change from one advertisement to the next made quickly at the completion of such interval of time; to provide means fonloeking the slide holder in stationary position during the interval or' display ot' each advertisement; to introduce a changing color on the :ulvertisements during their intervals of display; to provide a suitable housing for the device, having a screen, whereby the device maybe transported from place to place and be ready for immediate use; to secure simplicity of construction and operation, and to obtain other advantages and, results as may be brought out in the followingr description.

ln the accompanying drawings, in which like numerals of reference indicate the same parts throughout the several views, Figure l is a perspective view of the advertising display device removed from its case; l? ig. 2 is a horizontal section through the device with its case in position., on line AHA, Fig. 3; F ig. 3 is a vertical transverse section on line iii-uli, of Fig. Q, looking in the direc'- tion indicated by the arrows; Fig. 4-

a vertical longitudinal section through a. portion of the device showing the slide carrier in diametric section; and Fig, 5 is a detail persjiective view of a portion of the groove 'extending around each slide holder, showing one of the springs for frictionally retaining the slide in position.

In the specific embodiment of the invenpro- tion illustrated in said drawings, the reference numeral l indicates a suitable base for supporting the various mechanisms and 2 is a lantern housing of any well-known type which is supported midway between the lateral edges of the base 1 at one end and adapted to contain any suitable lamp or lighting means (not shown) o1 well-known and approved type. As is usual, the rear end of this lantern housing 2 is provided with a door 3 for access into the interior thereof, and the front end of the lantern housing is provided with a lens holder 4 carrying a lens 5 as is customary in lantern construction. Axt a spaced distance in front of the lens 5 is mounted a rotary slide carn rier 6, having its axis of rota-tion parallel to the axis of said lens in the preferred con struction. This slide carrier 6 preferably comprises a disk-like body portion 7 radially recessed or slotted at its periphery as at 8,8, and around the three edgesof each of these slots on the front side of the body portion, is integrally formed or attached a U-shaped slide holder 9 grooved about its inner periphery as at l0 for the slidable intraduction of a slide ll of greater width than the slot 8 in the body portion whereby lateral displacement ot the slide l1 from the groove 10 is prevented by engagement of its margin with the overlapping portions of the body portion 7 and the slide holder 9. Each of these slides .ll is preferably of a transparent material such as glass and bears the advertisement (not shown) which it is desired to project. The slots 8 about the periphery of the body portion are adapted to be brought intermittently in registration with the lens 5 of the lantern so that light projected therethrough will pass also through the slides in the slots.

Arranged in front of the position of the slides when in alinement with the lens 5 and in substantial axial alinelnent with the. lens 5 is a telescopic focusing lens holder 12 of any suitable type well-known in the art for focusing the image onto a screen. We have shown this focusing leus holder supported by a lbracket 13 extending outward from the top of the lantern box or housing 2 over the slide carrier G and downward as at M- in front of the same to the stationary portion l5 of the telescoping lens holder. As means for raising or lowering the image or adver` tisement in, its projected' position upon the screen We extend the downwardly extending arm 1a of the bracket below the ocusinglens holder .12, as at 16, and provide through this extension a screw 17 to bear against the lateral surface ot the body portion of the slide carrier 6. Obviously by screwing the screw 17 inwardly the image will be raised on the screen and by loosening or retracting the screw will loiver the projection of the image.

In order to revolve the slide carrier G so as to successively present the slides 11 carrying the advertisements in registration With the projecting lenses, said carrier is mounted upon a shaft 1S extending longitudinally of the base and supported in properly spaced relation there-above by standards 1i), 20 provided with suitable bearings 21, 22 at their upper ends. lVe provide an intermittent drive for said carrier, and tor this purpose secure, as by screws 23, 23, a gear to the carrier in axial coincidence therewith and also secured to the shaft 1S as by a set screw 25 through the hub 26 of said gear. 1t may here be noted that said hub 1s arranged to hear at its outer end against the adjacent 'end of the bearinv 21 to prevent lateral movement or displacement et. the carrier 6 away Jfrom the lantern and that movement toward the lantern prevented by a cellar 27 adjacent the outer end ot the shaft 18 and bearing on the outer end of the other bearing 22. y

A continuously revolving disk or plate 28 is mounted adjacent the gear 24 and in the same plane therewith, and provided one circumferential point with a .single projection or tooth 29 adapted at each` revolution to engage in a slot 30 of the gear 2t, it being understood that the gear 2t is provided about its periphery with slots Il() at spaced intervals so that engagement ot the tooth in one slot 30 will turn the carrier 6 until said tooth parts mesh with that slot and will place the next slot in position to receive the tooth 2O When/it revolves suliiciently to enter the same. Theends oi the teeth of the gear 24 between thejslots 3 are cylimlrically concave, as indicated at 3l, the artis ol curvature being coincident with the axis about which the disk 28 revolves. rthe dislr 2S is preferably circular' for the major part of its eireumfercnce, except adjacent the tooth 2S) where it is recessed toward thel tooth for the proper operation thereof", the radius 'for the circular portion being equal to the radius of curvature of the conceived ends 3 lf ot' the teeth oi the gear 2li whereby as the disk revolves With its tooth but ot (mgagcment with the slots 30, the periphery o'l` the disk is in slidable engagement. with the gcaii 24. lut as the disk 28 projects inside of the maximum circumference ot the gear by virtue of the concaved teeth, the gear 2l: is positively held against any rotative movement until the dish has revolved suhcieully for the front oit tooth 29 thereof to engage one of the slots 30 and carry the gear forward another step when the disk again locks the gear against rotation.

The disir 28 is driven ina continuously rotative direction by any suitable means such as by a motor 32 connected thereto by any Convenient and suitable means adapted to the purpose. As here shown, the disk 29 is nenrotatably secured upon a counter shaft 32 in its proper relation to the gear 24, which shaft is journaled in suitable bearings 33, 34C of standards 35, 36 and preventedfrom the loneitudinal moveinentntherein by means of the nnb 37 on the dislr bearing against the end of the bearing toward the lantern, and a collar preventing longitudinal movement toward the lantern by being positioned on the relatively opposite side of the other bearing and secured. to the shaft thereat. Adjacent the end of this counter shaft 32 a worm wheel 3) lined thereon meshing with a worm 4() on a transverse shaft L'l1 carried in stzuulards 2- i) at the nu LU the base 1.b 'ilus transverse shaft Ll1 has near its other end a pulley 14 re eeiviing a belt do trom the motor 32, it being understood that the proper speed oi the dislrniay be effected by proportioning the size of the 'pulleys and worm drive to corn respond to the norm. l speed of the motor,

here shown, the cnil ot the transverse yshaft l1 away Vfrom the ivm'ux is pr. \'ided with a pulley 4l@ For drivingr a belt fifi'. This belt drives another pulley l-S adjacent. the lantern housing and carried by a transverse shaft 40 supported by the depending ears 5l), 50 ot a bracket 5l secured to the bracket l'l carrying the telescopic ions holdcr 12. This shaft Li9 carries a suitable drum h2 ovcl which travels a ticxible ribbon or lihn 5?) extending substantially vertical downward between the lens in the lantern and the slide carrier 5 in the pat-h of the light Afrom the hintern and traveling around a lower or idle drum 5+ heldv by a suitable braelfct 55. 'lhis lihn 53 is piclerably endless and transparent to light but having various colors throughout its length so that as the drum 52 revolves the same a. variation in the color of light projected with the advertisement takes place while each such :ulvertisement is being exhibited. lt will be noted that the two opposite runs ot' this lilm both lie in the path ot light between the lantern and slide, and that since said runs travel in diil'erent direct ions there is an intermixingand changing oi colors, due to dillierent portions of the film coming opposite each other, whiclu Mtb momes end open, While the other section 57 is proceive the other section 56.

vided at its front with a screen 59 such as ground glass and its back end open to re- The lens may therefore be .focused to project the advertisement upon the inner side of the screen 59 and the device operated within said tele scopic sections. With a screen 59 as above suggested, the advertisement may be read from the outside and can of course by proper manipulation of the telescopic case sections and the lenses, be made of any desired size within the limits of the screen. It is to be understood that this particular construction is especially adapted foruse in show windows where it ymay be set and attract the attention of passers-by, but of course it is within the scope of the invention to use the same in other Ways and to construct it on a larger scale if desired for bill-hoard adver- 'tising 'and the like.

Preferably the roove slideholders 9 have arranged upon t e front walls of their groove l0, and in the opposite arms of the U-shaped holder, leaf springs 60, 60 secured at one end as at 61,:see Fig. 5 and ada ted at the other end to press against the sli e to retain the same, in place. Obviously by this 4arrangement the slide may be small enough to move slightly edgewise in its holder and thus be adjusted to exact position under the yielding` pressure of said springs.

lVe do not limit ourselves to the precise constructions and arrangements shown and described, since the same are given in some detail merely for the sake of clearness, and do not wish to be understood as restricting our invention except as required by the appended claims when construed inthe light of the prior art. Parts of our construction may also be employed to the exclusion of other parts without departing from the spirit and scope of the invention.

Having thus described the invention, what we claim is- 1. The combination with a projecting lantern and means for introducing a slide into the path of projection, of an endless film variously colored for diderent portions of its length and having oppositely traveling portions of itself in the path of lighthetween the lantern and said slide-introducing means, and means for operating said film.

2. Thecombination with a projecting lantern and means for introducing a slide into the path of rojection, of rollers on opposite sides of said) path of projection, an endless film variously colored for different portions of its length passing around said rollers and returning from each one to the other across the path of projection in substantially parallel lanes, and means for driving one of said rol ers.

3. The combination of a projecting lantern, a bracket extending forwardly from the top of said lantern and havin a downwardly extending arm, a lens hol er carried by said arm, means for introducing a slide between said lantern and`-lens holder, a roller supported on said bracket above the path of light, a film variously colored for dlderent portions of its length extending over said roller with portions of itself depending between said lantern and downwardly extending arm of the bracket across the path of light, means below the path of light for guidin `'said film, and means for causing said co or hn to travel.
